Quantum Properties of Two-Mode Squeezed Even and Odd Coherent States
Jing Zhang, Wei Wu, Meng Shao-ying · Communications in Theoretical Physics · 2007
Two new types of quantum states are constructed by applying the operator s (ξ) = exp (ξ* ab −ξ a † b † ) on the two-mode even and odd coherent states. The mathematical and quantum statistical properties of such states are investigated. Various nonclassical features of these states, such as squeezing properties, the inter-mode photon bunching, and the violation of Cauchy–Schwarz inequality, are discussed. The Wigner function in these states are studied in detail.
